This natural area, managed by the Arkansas Natural Heritage Commission, includes more than 400 acres of sandhill barrens and adjacent woodlands. Knowing that botanical riches were abundant in this preserve, Meredith and I pressed ahead and observed many interesting plants. We found the barrens white with jointweed (Polygonella americana) and cottonweed (Froelichia floridana) in full bloom. Other plants were also blooming, including scratch daisy (Croptilon divaricatum), elegant gayfeather (Liatris elegans), Louisiana goldenrod (Solidago ludoviciana), purple false foxglove (Agalinis tenuifolia), smooth yellow false foxglove (Aureolaria flava), forked blue curls (Trichostema dichotomum), and many-flowered buckwheat (Eriogonum multiflorum) to name a few. See a more complete plant list below.

Photo 2: Bees and other pollinators were busy on the tiny white or pale-pink flowers of the jointweed.

After the hike we were thirsty and drank deeply from the poison spring. There were no after-effects from drinking the spring water. However, I have noticed that a third eye has appeared in the center of my forehead. It sees infrared and operates independently of my other eyes, constantly scanning my surroundings. Very cool. I am sure its appearance is just a coincidence.

Photo 3: Each cottonweed (Froelichia floridana) flower spike is densely packed with white woolly flowers that are arranged in 5 spirals. When mature, the flower heads take on a cottony appearance.

Meredith, a long-time ANPS member, deserves much credit for faithfully monitoring and photographing native plants in the Poison Spring area for many years. Speaking on behalf of the field trip attendees, I thank him for leading this interesting field trip.

Photo 4: Purple false foxglove (Agalinis tenuifolia) plants, with their small but eye-catching rose-purple blooms, were scattered throughout the area.

Photo 5: A single bloom of the pink wild bean (Strophostyles umbellata) stood out against the parched sandy soil of the barrens.

Photo 6: Easy to overlook, we found ground-hugging heartleaf spurge (Euphorbia cordifolia), with its tiny flowers and red stems, growing beside the trail.
